Greetings,
    It appears that even the manufacturer is unable to control the 
pinning, so good luck. Pinning these is like trying to shovel sand.  
And that is what it seems like as you repin the action, only to see it 
begin to flop loosely around, springs having a carnival with the rep 
pinning so loose, etc.
    I have reamed them out to the loosest allowable amount and seen some 
success, but a year later, there is still a few here and there that 
have either regained their grip, or given up the grams and are floppy 
loose.
    I think this may be one of the reasons that the WNG hard bushings 
will be a prime attraction for the new composite parts, never mind the 
stability of the flanges!
Regards,

>>I've got a Steinway action that is seizing everywhere: jacks, hammer 
flanges, etc. Anyone found a good controllable solution short of 
repinning everything or changing parts? I know, alcohol/water w/ heat 
is the recommended approach but it produces very inconsistent results 
in the hammer flanges in my experience.David
